Update 2: Developer Double Fine has chimed in on the fate of Brutal Legend, stating that the Jack Black-starring action-adventure title "is fine."

Update: Sierra has assured that Ghosbusters "will not be cancelled", but offered no further details on the title or any of the others believed to be on the chopping block.

Original Story: In the wake of the recently completed Activision Blizzard merger, the company has revealed that only five franchises from Vivendi Games' Sierra portfolio will be making the transition to the newly-formed company's publishing operations.

Endangered titles Brutal Legend (Left) and Ghostbusters (Right).

The titles and franchises confirmed to make the leap include Crash Bandicoot, Spyro the Dragon, Ice Age, Radical Entertainment's Prototype and a yet unannounced title. Those remaining titles formerly slated for publishing deals with Vivendi Games, however, could now be without publishers.

"The only [Vivendi] franchises that Activision Publishing will release are based on Crash Bandicoot, Ice Age and Spyro, as well as Prototype and one other game that has not yet been announced," an Activision Blizzard representative told GameSpot. "We are reviewing our options regarding those titles that we will not be publishing."

The remaining Vivendi Games portfolio includes Double Fine's Brutal Legend, Terminal Reality's and Red Fly's Ghostbusters, A2M's Wet, Starbreeze Studios'... Read more

Radical Studios' open-world action title Prototype has been delayed to an unspecified 2009 release date, GameSpot reports.

The game was originally scheduled for release on the PlayStation 3, Xbox 360 and PC this coming fall.

"Since its announcement, Prototype has been regarded by many as groundbreaking and taking the open-world genre in new directions, and in the simplest explanation possible, we need more time to deliver the game the team initially set out to create," said publisher Sierra Entertainment.

Publisher Sierra has supplied us with a large number of new screenshots for its upcoming releases, including Ghostbusters, Prototype, and World in Conflict: Soviet Assault.

Sierra today announced Prototype, an open-world game by Radical Entertainment set to debut on the PC, PlayStation 3 and Xbox 360.

Prototype's lead character--a guy haunted by his past and fighting a secret war in New York City--is not Max Payne, but Alex Mercer, a very different character. Mercer can use shapeshifting powers to steal the skills and abilities of his enemies. This may sound mundane in a video game sense, like Grand Theft Auto crossed with Kirby, but Radical is focusing on providing a free-form movement system to provide "over-the-top action" across the urban landscapes.

"Prototype can climb or wall-run across any surface, jump 30 stories high, and destroy anything that crosses his path,” said Radical president Kelly Zmak. Radical is responsible for games such as Hulk (PC, PS2, Xbox, GCN) and Scarface: The World is Yours (PC, PS2, Xbox).
